Today, Bian Xiao Automobile briefly introduced to friends. The analysis of ternary lithium battery shows that ternary lithium battery does have better characteristics than lithium iron phosphate battery, but why is its development hindered? The key to the development of new energy vehicles is also the development of key batteries that plague mobile digital products. Today, the car editor of this station took a friend to look at the analysis of ternary lithium battery, hoping to solve the problem for friends.
BYD ternary lithium battery and analysis of ternary lithium battery
Lithium battery with lithium nickel cobalt manganate (Li(NiCoMn)O2) ternary cathode material as cathode material. According to Tsinghua University Gao's explanation, the "ternary" material mentioned in this survey refers to ternary power battery. Generally speaking, the anode is ternary and the cathode is graphite. In practical research and application, there is another anode that is ternary and cathode is lithium titanate. It is commonly called "lithium titanate". Its performance is quite safe and its service life is quite long. It is not a so-called "ternary material"
Advantages Ternary lithium batteries have higher energy density and better cycle performance than ordinary lithium cobaltate. Now, with the continuous improvement of formula and structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide battery.
Disadvantages: ternary power lithium batteries generally include nickel-cobalt aluminate lithium batteries and nickel-cobalt manganate lithium batteries. Because the high-temperature structure of Ni-Co-Al is unstable, the high-temperature safety factor is poor, and high pH value is easy to cause monomer flatulence, which leads to danger, and now the cost is high.
In contrast, ternary lithium polymer does have better characteristics than lithium iron phosphate battery, but why is its development hindered? The key to the development of new energy vehicles is also the key that puzzles mobile digital products &; mdash& The development of mdash battery. How to ensure that battery technology can meet the growing needs of consumers in a safe situation is not only the pursuit of people in the automotive technology-related industries, but also the pursuit of researchers in various fields.

When it comes to buying new energy vehicles, most consumers may think of&; Ldquo preferential policies &; Although rdquo is a bit embarrassing, it is indeed a very real reason. In the domestic sales environment, new energy vehicles need to be developed, but not just because &; Ldquo environmental protection &; Rdquo's long-term mission. The advantages of new energy vehicles in selling price and maintenance cost have really attracted the favor of most consumers who are still concerned about the cost of vehicles.
but it is possible that some consumers will temporarily stop their curiosity about new energy vehicles for some reasons, because almost all kinds of spontaneous combustion events of new energy vehicles will scare them. This is why I need to write this article today. If you know that you don't understand the fundamentals of new energy vehicles-the advantages and disadvantages of energy modules, and you don't know the precautions during use, I think this is no different from buying a time bomb around.
the key to the development of new energy vehicles lies in whether their experience can rival or even surpass that of traditional diesel locomotives, and whether they have more outstanding advantages in the purchase and after-sales links. In my opinion, the key to the development of new energy vehicles is also the key to mobile digital products-the development of batteries.
The above is a brief introduction of BYD's ternary lithium battery and the analysis of ternary lithium battery, which was introduced to a friend by Bian Xiao. Today, this car side Xiao arranged and shared BYD ternary lithium battery and ternary lithium battery analysis for friends. How to ensure that battery technology can meet the growing needs of consumers in a safe situation is not only the pursuit of people in the automotive technology industry, but also the pursuit of researchers in various fields. This is the end of the introduction of automobile series. If you want to know more about new energy vehicles, please pay attention to this website.
